Abstract- This paper presents an X-band voltagecontrolled hairpin resonator oscillator using GaAs MESFET varactor. To get wide tuning range, the hairpin resonator is combined with the MESFET varactor. It is incorporated into the series feedback oscillator. The measurement of the oscillator showed the frequency tuning range of 11.15 MHz with the output power flatness less than 0.10 dB at the center frequency of 8.836 GHz. The fundamental output power was 12.34 dBm and the second harmonic was suppressed by 􀋰32.04 dBc, and the phase noise performance was 􀋰95.78 dBc/Hz at 100 kHz offset. Index Terms- GaAs MESFET, microstrip hairpin resonator, oscillator, phase noise.
